Hi how do I move the logo from the top left to the center of the featured image above the search bar in the home page of the Supreme Theme?

I followed instructions:

Insert the custom CSS code below into GD > Design > Scripts > Custom Style CSS to fix this.

function gd_custom_home_logo() {
?>
<div class=”gd-custom-logo”>
<div class=’site-logo’>
‘ title='<?php echo esc_attr( get_bloginfo( ‘name’, ‘display’ ) ); ?>’ rel=’home’>‘ alt='<?php echo esc_attr( get_bloginfo( ‘name’, ‘display’ ) ); ?>’>
</div>
</div>
<?php
}
add_action( ‘sd_homepage_content’, ‘gd_custom_home_logo’, 9 );

and then

.sd-homepage #site-header .site-logo-wrap {
display: none;
}

HOWEVER, it did not work. Any suggestions?
